An excellent precision die casting designer is not only required to be able to draw drawings with software, but also to be familiar with the manufacturing process of precision die casting mold and the production process of precision die casting, and design the mold with the simplest mold making and the most convenient production operation according to the requirements of different products. Precision die casting design is the most fundamental link to ensure the quality of precision die castings. The rationality of its structural design and process directly determines the difficulty of die making, product dimensional accuracy, precision die casting process parameters, production and installation efficiency and so on.
Aluminum precision die casting has the advantages of high production efficiency, low processing cost, high dimensional accuracy, good surface quality and good overall mechanical properties; However, it is easy to produce defects such as pores, flow marks, scratches, depressions, cracks and under casting in the process of casting. How to avoid the above problems in the process of precision die casting, the designer needs to make a comprehensive evaluation in the structural design of precision die casting and make a reasonable layout in the structural design of parts
Precision die casting is a technology used for mass production of metal products and components, and the design of precision die casting die is one of the most important steps in this process, because the shape and properties of the die directly affect the final product. The precision die casting process uses high pressure to press the molten metal into the mold, and the mold with accurate specifications is required to complete the task.
Mold design will affect the shape, configuration, quality and uniformity of products produced by precision die casting process. Improper specification will lead to tool or material corrosion and product quality decline, while effective design will improve efficiency and production time. The first mock exam is the cavity, but not only the number of products that can be produced by a mold. The location of the core is also important. Is it easy to demolde the mold and so on?
In addition, the clamping line or parting surface of the die connects different parts of the die together. If the parting line is positioned incorrectly or deformed due to working strain, the material may penetrate into the gap between the molds, resulting in uneven forming and too many joints.
